Peter Travers is not only confident that The Social Network, director David Fincher's retelling of Facebook’s beginnings, will prove to be the best movie of the year, but that it’s the film to define the last decade. Jesse Eisenberg stars as Harvard undegrad and Facebook founder Mark Zuckerberg, delivering the best performance of his career. Justin Timberlake, Andrew Garfield and Armie Hammer also give award-worthy performances. But the real star of the film is Aaron Sorkin's screenplay, which Travers calls "a model of how it's done." Rounding out this four-star film is Trent Reznor's stirring score.
